Opis (eng)

This study investigated the presence of residues of eleven coccidiostats in unmedicated feed intended for broilers in the withdrawal phase, with the aim of assessing potential cross- contamination during feed production. Between 2023 and 2024, a total of 341 feed sam- ples were analysed, using validated LC-MS/MS methodology, for amprolium, diclazuril, halofuginone, lasalocid, salinomycin, maduramycin, monensin, narasin, nicarbazin, robe- nidine, semduramycin. Detected concentrations ranged from below the limit of quantifica- tion to 85.0 mg/kg. Non-compliant samples were identified for diclazuril (2/243), lasalocid (1/328), salinomycin (12/329), maduramycin (11/324), monensin (6/324), narasin (6/315), nicarbazin (2/327), and robenidine (7/333). The highest detected concentrations per analyte were: diclazuril 0.133 mg/kg, lasalocid 1.33 mg/kg, salinomycin 85.0 mg/kg, maduramycin 0.834 mg/kg, monensin 25.30 mg/kg, narasin 58.15 mg/kg, nicarbazin 33.70 mg/kg, and robenidine 35.2 mg/kg. Amprolium, halofuginone, semduramycin were not detected in any feed sample. Overall, 42 out of 341 feed samples (12.3%) exceeded the maximum permitted levels, indicating insufficient cleaning of production lines and inadequate separation be- tween medicated and non-medicated feed. The occurrence of such residues in feed intended for broilers in the withdrawal phase poses a risk of non-compliant residues in edible tissues, highlighting the need for stricter hygiene protocols, improved quality control in feed mills, and continuous monitoring to safeguard food safety and public health.
